For removal/installation of Bearing retainer [2] LUBRICATION Put 8g of Makita grease N No.1 in the gear room of Gear housing complete. Fig. 1 Fig. 2 Fig. 3 P 2 / 7 [3] DUSASSEMBLING AND ASSEMBLING CAUTION: Be sure that the tool is switched off and unplugged before starting disassembling/assembling. CAUTION: When using a blower for cleaning, always wear safety goggle to protect your eyes from metal dust. [3] -1. Replacement of Base DISASSEMBLING 1) Remove (+) Pan head screw M5 from the hinge portion of Base while holding Hex lock nut M5-8 with wrench 8 or the like so that it cannot turn together with the screw. (Fig. 1) 2) Release depth adjustment lock, and then remove Pan head screw M4x8. Now Lock plate can be removed from the depth guide of Base. Remove Hex nut M6, and now Lock lever section can be disassembled as illustrated in Fig. 2. ASSEMBLING Do not forget to put (Part No ) between Gear housing (blade case) and the depth guide of Base. (Fig. 3) Be careful not to place (Part No ) there. The two Flat washers can be easily distinguished by outer diameter as illustrated in Fig. 4.

(Fig. 5) 2) Remove Carbon brushes and four M5x40 Pan head screws. Now Motor housing can be separated from Gear housing (blade case). (Fig. 5) Note: Be careful not to lose the compression spring of shaft lock when taking Armature out of Motor housing. 3) When removing Field from Motor housing, be sure to disconnect lead wires from Trigger witch beforehand. The switch can be reached by removing two 4x18 Tapping screws and two M5x12 Pan head screws on Housing (R) side to separate Handle (R) from Handle (L). (Fig. 6) CAUTION: At this time, treat the lead wires from Field carefully because they are still connected with Handle. Remove Lead cover by removing Tapping screw CT4x12. Tapping screw 4x18 Trigger switch Remove Brushes. Remove four M5x40 Pan head screws. Pan head screw M5x12 [3] -3. Disassembling/Assembling of Safety Cover, Bearing Box and Gear Housing (Blade Case) DISASSEMBLING 1) Remove Retaining ring on Safety cover using Retaining ring pliers ST-2N (1R003). At this time, hold the ring with gloved hand so that it cannot fly off. 2) By removing Safety cover, three parts can be disassembled in the following order; Washer 42/ Spacer/ Thickness ring (See Fig. 7.) Remember this order for reassembling. 3) If Safety cover does not move smooth, remove metal dust from each part and apply machine oil. 4) Bearing box can be removed by removing two M5x12 (+) Countersunk head screws. (Fig. 8) If it is hard to remove, turn Bearing box a little, and then lift it up using two Bearing extractors (1R263). Note: When reinstalling the countersunk head screws, apply an appropriate amount of THREE BOND 1321B/1342 or LOKTITE 242 to them before tightening.
